Expectations for the social media giant's IPO are high, and after opening well above their offer price, shares of Twitter could head even higher in the months to come.

Keith Bliss at Cuttone & Co: "If they had opened that stock at the IPO price, you would have had a lot of people that would have sold their stock at that price – and that is their right to do that - but they would have ended up missing out on $20 worth of gain. So the price discovery process allows you to discover where people are really willing to buy the stock and where people are willing to sell the stock."

Ted Weisberg, who has been on the floor for 40 years, on the Twitter IPO: "From my perspective, it is just another day at the shop, though it was a lot more crowded on the floor given all the external interest. Things are still pretty active down here. The stock really had the attention of the public."

Dan Primack argues that Twitter left a lot of money on the table by not pricing its IPO correctly:

Twitter itself obviously wanted a bit of price pop for PR and employee morale purposes, but here's something else employees could be thinking about today: Had Twitter priced at $45.10 per share and used the extra proceeds to give out holiday bonuses, it would have worked out to more than $580,000 per employee. How's your morale feel now?

So about 11.8 mln shares traded on the opening cross at $45.10 according to Thomson Reuters data; that's in line with what the NYSE has said as well. Stock at $48 now

All tweets share the same anatomy. To examine the guts of a tweet, you request an “API key” from Twitter, which is a fast, automated procedure. You then visit special Web addresses that, instead of nicely formatted Web pages for humans to read, return raw data for computers to read. That data is expressed in a computer language—a smushed-up nest of brackets and characters. It’s a simplified version of JavaScript called JSON, which stands for JavaScript Object Notation. API essentially means “speaks (and reads) JSON.” The language comes in a bundle of name/value fields, 31 of which make up a tweet. For example, if a tweet has been “favorited” 25 times, the corresponding name is “favorite_count” and “25” is the value.
